In this fourth book of the Wicked Witch, Hilda and William have to take on a witch called Zelda. A magical battle is unavoidable...

Excerpt: Hilda and William fell away sideways, making room for the dragons to pass them without harm once again. It was as if an aircraft carrier were rushing by. The magical couple, well versed in the art of dragon-catching, pulled round and started following the dragons that were flapping their mighty wings to turn. The magical people knew that this maneuver was the best moment to get to the dragons as the animals would not be paying much attention to their tails. Turning fast in full flight was a task for these big beasts. Wands drawn and magic ready, Hilda and William raced towards the dragons. Bolts of power bounced away from them, intended to immobilise the dragons and hold them suspended for transport. They had done that so often in the past weeks, it had become routine.
